It takes some time for the "heal power" to kicks in,but when he takes the badages off you will see the steam coming outof his arm.And about Eren,he wasn't physicly hurt,but his body was tired from the fight and from the stress during the fight(but in the anime he ented in that "deamon form",so that probably took a tool on him).The next episodes are gonna be insane.

Well, that was disappointing. ]No fight. I was expecting to see the scouts start fighting Reiner and Bert. The transformation sequence was pretty cool though. Especially the music playing during it. The way Mikasa was looking at Reiner and Bert just screamed murder. The rest of the episode was good. . Now we got to wait for episode 7.
